WIRE-COATING FOR DRAWING.

SPECIFICATION formingpart of Letters Patent No. 282,055, dated July 31,1883.

Application filed April 1-2, 1883. (No specimens.)

To all whom it may concern.-

Be it known that I, ADDISON B. OLEMENoE, of the city and county ofWorcester, in the State of Massachusetts, have invented certain new anduseful Improvements in the Art or Process of Wire-Drawing; and I dohereby declare that the following is a full, clear, and exactdescription of my said invention.

To enable those skilled in the art to which my invention appertains topractice my said improved process, I will proceed to describe it more indetail.

The wire, preparatory for my coating, should be cleaned in a mixture ofoil of vitriol and water, and then rinsed or washed in hot water. It isthen in condition to be treated with my coating for drawing, whichconsists of a solution of acetate 1 of soda in water, and after saidcoating has been properly dried the wire is ready to be drawn throughthe drawing-dies in the usual manner.

It is better to preparethe bath for coating of suflicient size tocontain a considerable quantity, and thenimmerse the coils of wire inthe bath, which can be done with the machinery and appliances nowincommon use for coating wire.

The mode of preparing the solution for my coating is to heat a suitableamount of water in the bath, and then add and. dissolve the acetate ofsoda until a solution of proper strength is obtained, then immerse thewire, as before explained, and after the coating becomes hardened thewire is then ready to be drawn.

The coating to the wire obtained in the manner above described isadhesive, hard, smooth, and very uniform -on the surface, and in a largemeasure preserves the wire from rust after it is drawn, leaving it abright finish.

Having thus described my improved process in the art of coating wirepreparatory for drawing,=what I claim therein as new and of myinvention, and desire to secure by Letters Patent, is-

For Wires-drawing, a coating of acetate of soda, substantially as andfor the purpose set forth.
